IMPROVEMENT IN PAPER BAGS.`

To all whom it may concern:

Be it known that we, BENJAMIN SMITH, ADAM SMITH, and J AMEs AEKELL, ofCanajoharie, in the county of Montgomery and State of New York, haveinvented new and useful Improvements in Paper Bags; and we do herebydeclarevthat the following is a` full, clear, and exact descriptionthereof, which will enable others skilled in the art to manufacture thesame, reference being had tothe accompanying drawings, forming a partot' this spe citication, in Which- Figure l is a side View of a bagdistended, aswhen filled. Fig. i2 is a bottom view of the saine..Figs.3,4,5,6,and6*,represcntthelower portion of the bag in differentstages of the manufacture. Fie. 7 is a side view ofthe lower portion ot'the empty bag folded iat for trailsportation or the market. Fig. 8 is anedge View ot' the. same.

Similar letters of reference indicate like parts.

This invention consists in a novel mode of producing the bottom of apaper bag, whereby it is made double, and, when the bag is distended, itis caused to present a square or quadrangular form.

To make the bag, We first take a piece of g paper of quadrangulary formof the requisite length and width, and t'old it to produce alongitudinal lap, ti.her close to the fold or along an5T other portionof one side, paste the lap, press it, and allow it to dry. A tube, A, ofthe width ot' the lap is thus formed. This tube is then laid tiat andits two lower corners turned in at angles of forty-tive degrees to thesides, as shown at a a in Fig. 4, till the bottom edges, b b, meet, ornearly meet. The lower part is then folded over, as shown at U in Fig.5, to make the point dV lap over the turned-in portions i i of the sideedges. The bottom is then unfolded, when it presents the creasedappearance shown in Fig. 6, in which the creases are represented bydotted lines, those formed in the tube by the folds a and c beingindicated by similar letters, and those formed in the turnedincorner-pieces d d in making the fold c being indicated by the letters cc. Two vertical cuts, e e, are then made from the bottom in or ia littleinside of the creases c c', upto the diagonal creases a a. The portionsot' the eornerpieces d d outside of the cuts e `e arethen turned invertically from horizontal lines between the points where the said cutsmeet the creases a ct to produce the two creases g g to meet Hthecreases c c, and so form the square bottom,`

v the portions of the lines a a, above the cuts e c, as shown in dottedoutline in Fig. 6*, and the two portions ff, one on each side of thetube between the cuts e c, are then, one after the other, turned outwardand back over the p tube, and their inner sides (now turned out- Ward)pasted, and each, after having been pasted, is turned,` in between theportions d d. The said portions f f are thus pasted `to each other andto the portions d d, and these portions produce the quadrangular bottomwhen the bag is distended by lling.

lt' in the tir-st folding ot' the corner-pieces d d the edges b b bebrought close together,

and the fold c be made at a distance from the t point d. equal to thedistance from c to t' z', the whole of the quadrangular bot-tom of' thebag will be composed of four thicknesses ot' paper.

We are aware that it is common to crease` rangular paper bag with adouble bottom pro-` duced by folding and pasting inthe particle larmanner herein described.
